Messages Broadcasting Exploiting Device to Device Transmission

A method of broadcasting a message (m) among user equipment (UE0-8) in a broadcast area (115; 515) covered by a wireless communication network (100) is proposed. The wireless communication network comprises at least one radio base station (105; 420, 425; 505A-E) which is adapted to manage communications of user equipment in one or more respective served areas (110; 405, 410; 501A-E). The method comprises having the at least one radio base station identifying (210) user equipment comprised in the broadcast area; among the user equipment within the broadcast area, estimating (215) a set of transmitter user storing the message to be broadcasted; among the user equipment within the broadcast area, estimating (220) a set of receiver user equipment not storing the message and being able to receive the message sent by at least one transmitter user equipment through a device to device communication, and selecting (225) a subset of transmitter user equipment for transmitting the message ensuring that the receiver user equipment in said set receive the message with a predetermined confidence.
